It's Complicated: 11 On-Again, Off-Again Celebrity Couples

After months apart, Miley Cyrus and Liam Hemsworth appear to be back together again, following in the rocky footsteps of Kristen Stewart and Rob Pattinson, Selena Gomez and Justin Bieber, and other on-again-off-again couples.

Celebritologists had long ago determined that Miley Cyrus and Liam Hemsworth had broken off their engagement, but in mid-June the pair was spotted together in public for the first time in five months. And they were holding hands. So is the on-again-off-again couple actually a couple—again? As Cyrus told Rolling Stone in the latest issue, "I wear a ring every single day. I don't talk about my personal life, so that's enough of an answer."

Kristen Stewart and Robert Pattinson

For several years, Twilight costars Kristen Stewart and Robert Pattinson were coy about their off-screen relationship. "So much of my life is so easily Googled," she told British GQ in 2011. "I mean, it's, like, 'Come on guys, it's so obvious!'" But when news broke in July 2012 that Stewart had cheated on Pattinson with her Snow White and the Hunstman director, Rupert Sanders, Twihards took the news hard. As did Pattinson—despite her public apology, he moved out of the Los Angeles home they shared and their now-public relationship was officially off. Until it was back on—at least in public. The pair posed together at the premiere of the final Twilight movie and were spotted together, but a few months later Pattinson and Stewart put a stake in their love once again.
